Convert Number Words to Digits Convert English number words back to numeric values.

A Words to Number converter is a tool that translates English number words into their corresponding numeric values, enabling users to parse number words and convert them to digits. Developers and data analysts use it to process textual data containing number words, solving the specific problem of converting unstructured numerical text to structured numerical data. For instance, when dealing with text files or user input containing words like "one hundred twenty-three", this tool can accurately convert such phrases to their numeric equivalents.

The tool is particularly useful for handling compound numbers and scales, including ones, tens, hundreds, thousands, millions, billions, and trillions. It ignores the word "and" as a connector and supports "negative" or "minus" prefixes, allowing it to correctly interpret phrases like "negative forty-two". What makes this tool different is its ability to handle a wide variety of input formats, thanks to features like the `wordMap` and `scaleMap` dictionaries, which define mappings for words to numbers and scales respectively. These dictionaries enable the tool to accurately convert words to numbers online, making it a reliable word number converter.

It uses regular expressions to clean the input text, removing non-alphabetic characters and replacing hyphens with spaces, before splitting the text into individual words and processing them according to their definitions in the `wordMap` and `scaleMap`. This allows it to serve as an effective number word parser, capable of converting complex phrases like "three million five hundred thousand" into their numeric equivalents.
